  • the upper, lower, and intermediary apertures cooperate to define the interior space.
  • the lower annular component contacts the base in the attached condition of the heater assembly.
  • the jar assembly further includes a blade positioned within the jar upward of the heat transfer element, and an upper coupler coupled to the blade via a shaft that extends through a heat transfer element aperture defined by the heat transfer element.
  • the jar assembly is selectively coupled with a housing assembly of the blender assembly that includes the base, the motor, and the lower coupler, such that the jar assembly is operable to move between an operably coupled condition and a decoupled condition.
  • the upper coupler is operably coupled with the lower coupler, such that rotation of the lower coupler by the motor prompts rotation of the upper coupler.
  • the blender assembly further includes an intermediary coupler assembly that is positioned within the interior space of the collar and includes a first coupler, a second coupler positioned downward of the first coupler, and an intermediary shaft that extends between the first and second couplers.
  • the upper coupler is operably coupled with the lower coupler via the intermediary coupler assembly in the operably coupled condition of the jar assembly.
  • the heating element includes an annular puck that is positioned within the interior space defined by the collar, and a heater coil coupled to the annular puck.
  • the jar defines an upper opening and a lower opening, and the heat transfer element is configured to generally fill the lower opening, such that the heat transfer element functions as a bottom of the jar.
  • a heater assembly for a blender assembly includes a collar that defines an interior space, a heating element disposed at least partially within the interior space, and a biasing feature operably coupled with the collar and the heating element and being configured to bias the heating element in a first direction.
  • the heating element is operable to move relative to the collar in a second direction that is opposite the first direction against the bias of the biasing feature.
  • the collar includes a lower annular component that defines a lower aperture, an upper annular component that defines an upper aperture and is coupled to the lower annular component, and an intermediary annular component that defines an intermediary aperture and is positioned between the upper and lower annular components.
  • the upper, lower, and intermediary apertures cooperate to define the interior space.
  • the heating element is disposed at least partially within the upper aperture defined by the upper annular component of the collar.
  • the heating element includes an annular puck that is positioned at least partially within the interior space defined by the collar, and a heater coil coupled to the annular puck.
  • an upper surface of the heating element is elevated relative to the collar.
  • a blender assembly includes a base, a heater assembly selectively coupled to the base and having a heating element and a biasing feature that biases the heating element away from the base, and a jar assembly selectively coupled to the heater assembly and having a jar and a heat transfer element coupled to the jar. Coupling the jar assembly to the heater assembly prompts the heat transfer element to contact the heating element, such that the heating element moves toward the base against the bias of the biasing feature.
  • the term "coupled” in all of its forms, couple, coupling, coupled, etc. generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated.
  • elements shown as integrally formed may be constructed of multiple parts or elements shown as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connector or other elements of the system may be varied, the nature or number of adjustment positions provided between the elements may be varied.
  • the elements and/or assemblies of the system may be constructed from any of a wide variety of materials that provide sufficient strength or durability, in any of a wide variety of colors, textures, and combinations. Accordingly, all such modifications are intended to be included within the scope of the present innovations. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the desired and other exemplary embodiments without departing from the spirit of the present innovations.
